摘要：PROBLEM TO BE SOLVED: To surely position a moving object in first and second stop positions. SOLUTION: The linear movement mechanism 30A is characterized in that when a moving object 31A approaches a first stop position, a first spring 43 while coming in slide contact with the first cam spring sliding part 34d of the moving object 31A, is locked in the end of the first cam spring sliding part 34d, this movement causes an arm 42 to turn in one direction and the second pressed part 31j of the moving object 31A is pressed to a first stopper 21c side by the second pressing part 42c of the arm 42 to which the pressing force of the first spring 43 is transmitted, when the moving object 31A approaches a second stop position, a second spring 44 while coming in slide contact with the second cam spring sliding part 34e of the moving object 31A, is locked in the end of the second cam spring sliding part 34e, this movement causes the arm 42 to turn in the other direction, and the first pressed part 31i of the moving object 31A is pressed to a second stopper 21d side by the first pressing part 42b of the arm 42 to which the pressing force of the second spring 44 is transmitted.
